Windows 10 / Stop error: 0xc000021a

[Andre2314]

I am new to this website and to all the tjings that are posted here but I desperately need help to fix my stop error in Windows 10. When I started my computer it doesn't allow me to go to my accounts, it just crashes in a blue screen of death and it shows the stop error: 0xc000021a
Until now I tried every single solución that I've been able to search through the Internet and none of them worked, even in Microsoft oficial forums. I've even tried to reinstall Windows 10 into my computer for a fresh start but even that didn't helped me with my situation. Now I'm here in this forums trying to reach for help. Thank you.
